IDEFIX'97 works well too with DVD. I played some on my 1200PPC...

how do you play dvd's on a 1200? what do you need, and is it only limited to ppc? what setup is optimal?

Frankly, you can't.

yep i concur. you cant.

ppc is needed then! Piru?

ppc does not help. even 603p@240 is too slow.

i was curious of that so what is the discussion about on the top of this threat,"taken from the other current thread on the dvd on a4000? they claim to be able to watch dvd's on a 1200! :-?

If somehow you had a DEDICATED HARDWARE DECODER
on the A1200 then sure it would work. but with the limited color system. it would look like crap.

Software decoders need a minimum of 300mhz to play back smoothly.

But reading data DVDs should work fine. I think that is what the original post was referring to?

Thanks for the clarification,  it now makes sense! One last thing...viewing avi's which program would work best on an 060  without ppc?

I cant play DVD movies on my 1200 but I use my DVD Rom to make use of data.
So if I use Nero to put a load of Amiga files onto a DVD disc then I can see them and make use of them on my 1200 no problem. (Amiga folder on my PC from Aminet)
At least DVD can be good for that side of it.
But as they rightly say DVD movies No not a chance unless you got a powerfull Amiga ssytem.

And sadly that is something I have not got, so I will settle for my Apollo 030/40 for now.
Of course I use Aminet on my 1200 using AWeb, but letts face it my PC can download a ton and a half while my Amiga is stiil downloading a quarter of that.
Mike.

So are there any possibilities for DVD-playback with Amithlon or WinUAE?

Should be no problem, assuming you have software that can do it (say: mplayer compiled for 68k). Naturally you must use JIT and pretty powerful PC.

Then again, why not just use WinDVD or PowerDVD, you get nice surround sound and hw acceleration...

Bah, that would be too easy, i.e. no fun anymore. :-P
Btw, is there a 68k compile of MPlayer anywhere?

So what was the deal with amidog's amp2 which appears to have been written to play DVD's? see aminet or amidog's site

There is just not enough cpu power in even the fastest powerpc accelerator currently available. It might be possible if the shark is ever released or if someone write drivers for a hardware mpeg2 decoder.

Not if you use a gfx card.

It plays DVDs, assuming your system is fast enough.

Classic systems are not.

Cool, I will try AMP2 on Amithlon then. I'd prefer MPlayer if there was a 68k available somewhere? Seems more modern, more codecs.

And also Coldfire will be much too slow for that. At least at more than a 140x100 window.

C'mon Amiga  the next next evolution in digital media is here and we are still fiddling with speed, when blu-ray and HDDVD is the next step forward.  someone  get those old 400+ mhz ppc chips from some old macs and build a board for us hyperion port the damn Os and lets get caught up!  I'd do it my damn self if I knew how!!  I like to use my Amiga for everything..but I cant listen to streams, too slow, can't watch avi's, too slow can't watch a dvd,  yea too slow.  I'm afraid that the realism is amiga as aplatform is done, and all that's left is software which run on other systems. Now if their native software offer so much why are we still struggling with this platform???

That's a question only you can answer for yourself...

I wanna watch HDTV on my 'miga!

*SCNR*

I prefer VLC over PowerDVD/WinDVD though - plays just about anything around.

Hi,
My specs are : 1200+060/PPC@224/256Mb/FastSCSI/OS3.9 and MOS 1.4.5/GREX1200/Voodoo3-3000/FastSCSI Pioneer DVD6x.
I used amidog's amp2 and FroggerNG WOS and MOS.
I got around 12-18 fps@640/480 up to 1024/768, and the sound output with Paula in 56 Khz mode.
Few action movies can be seen properly, for the rest (anim) it's enough (theater and one man show).

I think non lagged dvd-movie playback on classic ppc have the following ingredients:

OS4 with native movie player (no switching orgy with 68k cpu)
As i remembered on pc a pentium 166 can handle with some pre-buffering.

On os3.9 (Os4 too) : SCSI HDD (I try some video clips playing from ramdisk, and i think the lack of speed of the internal ide port is the main bottleneck of the story)

Software with pre buffering,

@derringer3

Sorry but no go. The only ways to get working DVD playback are:

- have faster cpu
or
- have support for hardware decoder

Naturally things such as SCSI and video overlay (with gfxcard) are required, too.

double post...
Title: Re: playing dvd's on classic
Post by: Jose on March 22, 2007, 09:11:07 PM
The only hope would be a Cyberstorm with a CybervisionPPC as other gfx cards don't have enouph ZIII bandwidth, even when using Mediator or Prometheus. A PPC native OS would also be required and probably an optimized player. Only one I know is DV player. Oh and a SCSI HD to offload the CPU load.

Only ones with such a set up are probably some very few AmigaOS4 betatesters running DV player, maybe someone will post about it here:)

@cls2086

so with your set up you were able to view DVD's  at least some!

all I need now is a PPC@224.......right? :crazy:

and a SCSI hdd. As mentoined above. Ide has got cpu offload only in udma modes. (Not supported in any amiga interface)
SCSI has got this feature "built in". So with an ide any disk operation takes cpu time, scsi not.

as a point of reference, using DVPlayer on OS4, I can play PAL-DVDs in a PAL dimensioned window at full speed, albeit with a fairly heavy CPU load. my setup is:
AmigaOne XE, G3/800MHz, Radeon 7000 24 bit screenmode. this is using the IDE port on the mainboard. the OS version is the last public release by Hyperion (unless they lied, and theres been another since the last one ;-) )

I think one would really struggle to play that on even the most tricked-up A1200, let alone a 68k only job.

@agafaster: It would be a strange thing that in your config you cannot play dvd-movies.
